Optical characterization of H(2)O/HNO(3) films representative of polar stratospheric clouds and the mechanisms for heterogeneous chlorine activation on these surfaces.

摘要

Heterogeneous reactions on the surface of polar stratospheric clouds (PSCs) play a key role in polar ozone chemistry. Knowledge of the composition and phase of PSCs and the reaction mechanism for heterogeneous chlorine activation on their surfaces are required to accurately model stratospheric ozone chemistry. The optical properties of thin films of ;The real refractive indices and UV absorption spectra of thin ;The reactive uptake of
